* [PATCH] inode-diet: Eliminate i_blksize from the inode structureTheodore Ts'o2006-09-277-9/+5Star
| | | | | | | | | | | | | | | | This eliminates the i_blksize field from struct inode. Filesystems that want to provide a per-inode st_blksize can do so by providing their own getattr routine instead of using the generic_fillattr() function. Note that some filesystems were providing pretty much random (and incorrect) values for i_blksize.

* [PATCH] inode_diet: Replace inode.u.generic_ip with inode.i_privateTheodore Ts'o2006-09-2715-37/+37
| | | | | | | | | | | | | | | | | | | | | | | | | The following patches reduce the size of the VFS inode structure by 28 bytes on a UP x86. (It would be more on an x86_64 system). This is a 10% reduction in the inode size on a UP kernel that is configured in a production mode (i.e., with no spinlock or other debugging functions enabled; if you want to save memory taken up by in-core inodes, the first thing you should do is disable the debugging options; they are responsible for a huge amount of bloat in the VFS inode structure). This patch: The filesystem or device-specific pointer in the inode is inside a union, which is pretty pointless given that all 30+ users of this field have been using the void pointer. Get rid of the union and rename it to i_private, with a comment to explain who is allowed to use the void pointer. This is just a cleanup, but it allows us to reuse the union 'u' for something something where the union will actually be used.

* | PCI: Multiprobe sanitizerAlan Cox2006-09-271-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are numerous drivers that can use multithreaded probing but having some kind of global flag as the way to control this makes migration to threaded probing hard and since it enables it everywhere and is almost as likely to cause serious pain as holding a clog dance in a minefield. If we have a pci_driver multithread_probe flag to inherit you can turn it on for one driver at a time. From playing so far however I think we need a different model at the device layer which serializes until the called probe function says "ok you can start another one now". That would need some kind of flag and semaphore plus a helper function. Anyway in the absence of that this is a starting point to usefully play with this stuff Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
